FLIGHT International, 10 August 1972 183
likely on grounds that there is no need for much guidance
less than 150ft above runway.
The pilot would also like something with a visibility
performance guaranteed to exceed his circling minima.
These visual circling approach minima are certainly not set
or derived with Vasi performance in mind, and are inevit
ably applicable when flying, often in reduced visibility, on
to runways with limited instrument landing aids or none
at all.
Many such minima are quoted as two statute miles in the
USA and two nautical miles elsewhere. This means that a
circling aircraft may be flown up to four miles from the
centre of an airfield at a height that can be as great
as 1,000ft; the pilot may then be faced, in reduced visi
bility, with the task of adjusting the aircraft on to the
desired approach glideslope by visual reference. Inevitably
he has only the Vasis plus any high-intensity approach-
light and runway-light display that may be fitted.
Far too many accidents have been happening during
approaches on to non-instrument runways, and as a pilot I
think that it is not generally realised how difficult the
setting-up of a safe approach can be in some conditions of
visibility, bearing in mind the speed and inertia charac
teristics of many large jets. MAINLINER
